Definitely worth it. Lines are usually very short! Only one family is allowed in at a time. You don't feel like the next family is glaring at you trying to get you to finish up quickly! We've done one photo shoot at EpCOT with noone behind us and we had Minnie, Pluto and Goofy; we took family pics, pics with just the kids, pics with each character separately, etc...... We've had a great experience every time we've done it.
